@Sunshineandbluesky , I think what you are describing sounds perfectly "normal", for want of a better word.
Your loss is still so, so recent, in the scheme of things, that that all consuming feeling of fear and devastation is still very much to the fore for you.
There is such a lot of sorting out to do in the very early days (I heard it referred to as "sadmin" on another forum which I thought was very apt) that you almost float around on autopilot in a haze of disbelief initially and the sadmin is a distraction.
Then there are the funeral arrangements to organise and focus on and once that has happened - then what?
The new reality, is what comes next.
A reality we never wanted, or asked for - it just happened and we don't like it - give us back our old lives please.
But very, very gradually, we do adjust - little by little and at a snails pace we do start to develop our own new routines while hanging on to some of the old ones and, the grief, while always there, becomes less all consuming.
Those ludicrous things, that in the early days have us sobbing uncontrollably in public (it was seeing lamb chops in Mark's and Spencer for me - don't ask!) no longer reduce us to a weeping mess - they will forever more pull on our heart strings (of course they will because of the memories they evoke) but we each develop our own coping strategies in order for us to function in our own lives.
I fully appreciate that at this moment in time, you cannot ever envisage yourself in that position but it will come eventually - sadly, as @Hisredipad says, the time frame is different for everyone, and not linear as @Emptyandsad pointed out.
Sending huge hugs your way - hang in there Mrs.
